Definitions

  • the invention relates to an incendiary composition for a fin-stabilized kinetic energy projectile, which can be installed in the tail region of the projectile and, upon impact with the target, penetrates the target as a separate unit behind the penetrator of the kinetic energy projectile.
  • incendiary composition arranged in the tail section of the kinetic energy projectile can be selected such that it will be initiated by the shock wave generated during the impact with a corresponding target.
  • this reference does not offer further details concerning the concrete design of such an incendiary composition.
  • Incendiary compositions consisting of a metal sponge and an organic binder are known from reference DE-AS 29 01 517, wherein it is preferable if a metal sponge consisting of zirconium or hafnium and a binder of poly tetrafluoroethylene are used.
  • a metal sponge consisting of zirconium or hafnium and a binder of poly tetrafluoroethylene are used.
  • the above object generally is achieved according to the present invention in that a titanium sponge is used as the incendiary composition with epoxide resin or polyester resin used as a binder. Since the incendiary composition does not contain an oxygen carrier, it is relatively insensitive.
  • the titanium sponge particles Upon impact with the target, the titanium sponge particles are heated to the ignition temperature and continue to burn intensively when the particles are released and come in contact with the oxygen in the air.
  • the relatively brittle titanium sponge because of its low ductile quality is considerably more suitable for an incendiary composition than ductile materials such as zirconium powder, magnesium powder or aluminum powder.
  • the incendiary compositions according to the invention can also set on fire hard to ignite oils (such as diesel or hydraulic oil).
  • incendiary compositions according to the invention Another advantage of the incendiary compositions according to the invention is that during the normal state, they behave in the same manner as an inert material and can be ignited only with an extremely strong impact. Thus, the projectile can be handled safely even it the target is missed, provided the incendiary composition is not damaged.
  • the incendiary composition of a first advantageous embodiment of the invention consists of a mixture of 85 to 96 weight % titanium sponge and 4 to 15 weight % of the epoxide resin or polyester resin, and has a density between 1.7 and 2.8 g/cm 3 .
  • the incendiary composition of a second embodiment is therefore composed of a mixture of 65 to 86 weight % titanium sponge, 4 to 15 weight % of an epoxide resin or polyester resin and 10 to 20 weight % of boron powder, wherein the density of the incendiary composition is again between 1.7 and 2.8 g/cm 3 .
  • the grain size range for the titanium sponge is selected such that 30% of the titanium sponge particles have a grain size larger than 450 ⁇ m and 70% have a grain size smaller than 450 ⁇ m.
  • FIGS. 1 and 2 are, respectively, a longitudinal section view through a kinetic energy projective containing an incendiary composition according to the invention, before and after the impact with an armored target.
  • the number 1 refers to a large-caliber fin-stabilized kinetic energy projectile, for example as fired from tank cannons
  • the kinetic energy projectile 1 comprises a penetrator 2 and a guide assembly 3 that is attached to the rear of the penetrator 2 .
  • the guide assembly 3 essentially consists of a sleeve-type guide assembly carrier 4 with stabilizer fins 5 arranged on the outside and a recess 7 that extends in the direction of the longitudinal axis 6 of the kinetic energy projectile 1 and is closed off by this penetrator on the side or end facing the penetrator 2 .
  • the tail region 8 of penetrator 2 extends into a front partial region 9 of the recess 7 and is non-positively connected to the guide assembly carrier 4 , for example, via a threaded connection 10 .
  • a case 12 which contains an incendiary composition 14 that is ignited only when impacting with a target 13 (e.g., a tank) (FIG. 2 ), is located inside a rear partial region 11 of the recess 7 , which adjoins the front or forward partial region 9 on the tail side.
  • the incendiary composition 14 is arranged inside the recess 7 , such that it can be displaced in the direction of longitudinal axis 6 of the kinetic energy projectile 1 upon impact of the projectile on a target.
  • the penetrator 2 initially penetrates this wall 15 mostly unhindered. As soon as the guide assembly 3 hits the wall 15 , it is separated from the penetrator 2 owing to its large diameter and the connected resistance and either remains in the wall 15 of target 13 or continues to fly with considerably reduced speed as compared to the penetrator 2 . In the process, the stabilization fins 5 of the guide assembly 3 splinter and the case 12 of the incendiary composition 14 is torn, at least in some sections.
  • the torn case 12 flies from the opened-up opening 16 of recess 7 in the guide assembly carrier 4 behind the penetrator 2 and is smashed, e.g., at the rear wall or on objects located inside the tank, thereby releasing the incendiary composition.
  • the incendiary composition reacts with the oxygen in the air, so that a rain of hot sparks is sprayed far and results in considerable incendiary effect.
  • the incendiary composition is comprised of 85-96 weight % titanium sponge and 4-15 weight % of an epoxide resin or a polyester resin, and the density of the incendiary composition is in the range of 1.7 to 2.8 g/cm 3 .
  • boron powder is added to the incendiary composition that is now comprised of 65-86 weight % titanium, 4-15 weight % of an epoxide resin or a polyester resin, and 10-20 weight % of boron powder, and the density of the composition is in the range of 1.7-2.8 g/cm 3 .
  • the boron powder has a grain size equal to or less than 10 ⁇ m. The boron increases the combustion energy of the incendiary composition so that a correspondingly higher effect is achieved in the target because of the increased heat.
  • the grain size range for the titanium powder is such that substantially 30% of the titanium sponge particles have a grain size larger than 450 ⁇ m and 70% have a smaller grain size.
